  • a lubricating oil is used in marine applications for sterntube lubrication.
  • This is a bore through the hull through which the propeller shaft passes.
  • the propeller shaft is supported by a propeller shaft bearing, the so-called stern tube bearing.
  • the primary task of the propeller shaft is the transmission of the drive movement through the hull to the screw.
  • the bearing ensures low-friction movement and the seals for the sealing of the drive shaft, both to the engine room and the sea side. This seal is accomplished by a seal made of elastomeric material, such as e.g. FKM exists. Nevertheless, it can be expected both with the leakage of the lubricant into the marine environment, as well as with the penetration of the water into the stern tube.
  • the above machines are lubricated with lubricating oils. These are usually based on mineral oils, synthetic hydrocarbons, silicone oils and various polyethers and polyglycols.
  • the common biodegradable lubricants on the market are mainly composed of the following base oils.
  • Natural vegetable oils consisting mainly of mono-, di- and triglycerides of fatty acids and a small proportion of glycerol and free fatty acids. These may contain saturated as well as unsaturated hydrocarbon chains. Disadvantages of natural vegetable oils are their poor low-temperature behavior and the low thermo-oxidative stability.
  • Synthetic esters which are prepared mainly by acid-catalyzed reaction of carboxylic acids with alcohols. These starting materials can be obtained from biomaterials as well as from petroleum products. In contrast to the natural vegetable oils, synthetic ester oils are generally very temperature-stable. Your performance can be adapted to the respective requirements.
  • Polyglycols consisting of predominantly linear, but also partially branched polyethers, which are usually synthesized by ring-opening polymerization of ethylene oxides or propylene oxides. The higher the proportion of ethylene oxide, the more water the lubricant can absorb.

In the acid-catalyzed production of estolides from unsaturated fatty acids, the acid function of the fatty acid attacks a double bond of an adjacent fatty acid molecule and thus forms an addition product. The addition product can in turn react with another fatty acid. This results in higher molecular ester compounds, so-called estolides. In the synthesis, oleic acid is preferably used.
